Yatsugatake Southern Foot Highland Spring Water Group Yamanashi Prefecture | Complete Guide to the Charm and How to Visit the Spring Waters Selected as One of Japan’s 100 Best Waters
What is the Yatsugatake Southern Foot Highland Spring Water Group?
The Yatsugatake Southern Foot Highland Spring Water Group (yatsugatake nanroku kougen yuusui gun) is a collection of spring waters scattered throughout Nagasaka Town, Ooizumi Town, Takane Town, and Kobuchisawa Town in Hokuto City, Yamanashi Prefecture. In 1985 (Showa 60), it was selected as one of the Ministry of the Environment’s “100 Best Waters in Japan,” and is known as a premier spring water spot representing Japan.
Rainwater and snowmelt that fall on the water source forests of Mount Gongen on the southern side of Yatsugatake permeate through the igneous and volcanic rocks of Mount Anagasa, a stratified volcano, and become groundwater over many years. Passing through the aquifer beneath the Kiyosato Highland, it springs up at the surface around an elevation of approximately 1,000 meters, forming this beautiful collection of spring waters.
It is said that there are more than 50 spring water locations, each with its own unique landscape and water quality, serving as important water resources that support the lives and agriculture of local people. In the majestic landscape where Mount Fuji and Mount Kai Komagatake can be viewed, the spring waters at each location create beautiful scenery with water.
Reasons for Selection as One of the 100 Best Waters
The selection of the Yatsugatake Southern Foot Highland Spring Water Group for the 100 Best Waters was based on several important factors.
Abundant Water Volume and Stable Supply
These spring waters scattered around an elevation of approximately 1,000 meters play an extremely important role in this region where water supply is unstable. They maintain a stable water volume throughout the year and are an indispensable source of agricultural water for the region.
Excellent Water Quality
Groundwater filtered through volcanic rock contains moderate mineral content while remaining clear and transparent, with water quality suitable for drinking. Water polished by the natural filtration system is characterized by a mellow taste and refreshing flavor.
Deep Connection with Regional Culture
The spring water group has been closely connected with the lives of local people since ancient times. The historical water distribution system seen particularly at Sabui Spring Water conveys to the present day the wisdom of ancestors for fairly distributing water resources.

Three Major Spring Water Spots
Among the Yatsugatake Southern Foot Highland Spring Water Group, here are the three most famous and worthwhile spring water spots to visit.
Sabui Spring Water (さぶいちゆうすい)
Sabui Spring Water is the representative spring water spot of the Yatsugatake Southern Foot Highland Spring Water Group. Located in a forest near Kaishiraizumi Station on the JR Chuo Line, abundant water of approximately 8,500 tons per day springs forth.
Origin of the Name and History
The distinctive name “Sabui” (literally “three-fold”) originates from water disputes in the Warring States period. At that time, three villages fiercely competed over this spring water. To settle this dispute, a retainer of Takeda Shingen exercised ingenuity and placed a triangular stone pillar at the center of the water channel. This stone pillar divided the water flow evenly in three directions, allowing equal distribution to the three villages.
This historic water division system remains preserved today, and you can actually see the wisdom and ingenuity of your ancestors. The triangular stone pillar is called the “division box” and is preserved as a valuable heritage of water management technology.
Facilities and Surrounding Environment
It is developed as Sabui Spring Water Park, complete with a spring water pond, walking paths, and rest facilities. The park also has a museum where you can learn about the history of spring water, allowing for a deeper understanding of the water culture of the Yatsugatake Southern Foot region.
A walking trail along the clear stream is well-maintained, allowing you to enjoy nature in all seasons while strolling. Particularly during the season of fresh greenery and autumn foliage, the water’s-edge landscape is especially beautiful.
Otaki Spring Water (おおたきゆうすい)
Otaki Spring Water is a spring water spot located about a 20-minute walk from Kobuchisawa Station on the JR Chuo Line. True to its name, the sight of spring water flowing down as a small waterfall is striking.
Characteristics and Appeal
Otaki Spring Water stands quietly in the forest, enveloped in a mysterious atmosphere. The water volume is abundant, and the water temperature remains stable at around 10 degrees Celsius year-round, feeling cold in summer and relatively warm in winter.
The area around the spring water pond is covered with moss-covered rocks and trees, creating a fantastical landscape as if you had wandered into a primeval forest. In the silence where only the sound of water and bird chirps can be heard, both body and mind can be refreshed.

Spring Water Formation Mechanism
Let us explain the scientific mechanism of how the Yatsugatake Southern Foot Highland Spring Water Group is formed.
Water Source and Precipitation
The water source for spring waters in the Yatsugatake Southern Foot region is primarily rain and snow that falls on the southern part of the Yatsugatake mountain range, including Mount Gongen (elevation 2,715 meters). This region has relatively high annual precipitation, with particularly abundant winter snowfall.
Groundwater Infiltration and Filtration
Precipitation is absorbed by the soil of the forest and slowly permeates through the igneous and volcanic rock layers of Mount Anagasa, a stratified volcano. During this process, mineral components contained in the volcanic rock dissolve, while impurities are naturally filtered out.
Volcanic rock is porous with high water permeability, allowing water to infiltrate relatively smoothly underground. Conversely, as it passes through the fine pores of the rock, both physical and chemical filtration occur, forming clear groundwater.
Aquifer and Groundwater Flow
Water infiltrating underground is stored in the aquifer beneath the Kiyosato Highland. The aquifer is a highly permeable stratum with the capacity to hold vast quantities of groundwater. Through this aquifer, groundwater slowly flows southward.
Spring Mechanism
When groundwater reaches an elevation of approximately 1,000 meters, changes in geological structure cause it to spring forth to the surface. Low-permeability strata (impermeable layer) block the flow of groundwater, and water pressure pushes it up to the surface.
These spring points become numerous spring water spots including Sabui Spring Water, Otaki Spring Water, and Metori Spring Water. Spring points tend to be arranged linearly along geological structures, which is the reason they form a “spring water group.”
Water Temperature Stability
The water temperature of spring water remains stable at around 10-12 degrees Celsius throughout the year. This is because water flowing deep underground for extended periods is maintained at a constant temperature under the influence of ground temperature. The feeling that water is cold in summer and relatively warm in winter is due to the relative difference from external temperature.
Water Quality and Characteristics of Spring Waters
The water quality of the Yatsugatake Southern Foot Highland Spring Water Group has unique characteristics due to its formation process.
Water Quality Characteristics
Groundwater passing through volcanic rock contains moderate mineral content. Main mineral components include calcium, magnesium, sodium, and potassium, with hardness in the range of soft water to medium-hard water (approximately 50-100mg/L).
The pH value ranges from weakly alkaline to neutral, making it suitable for drinking. It is clear and transparent with no characteristic odor or taste. It is evaluated as mellow with a good taste and easy to drink.
Water Quality Preservation Efforts
To preserve the water quality of spring waters, forest protection and land use regulations are implemented in water source areas. Additionally, regular water quality testing monitors safety and quality.
Cleaning activities and environmental preservation activities by residents are also active, with efforts to beautify spring water surroundings and maintain the natural environment.
Spring Water Use and Contribution to the Region
The Yatsugatake Southern Foot Highland Spring Water Group goes beyond being merely a tourist resource and makes substantial contributions to regional society.
Use as Agricultural Water
